Hi all,

Sometimes it is necessary to have additonal (beside stdin/stdout/stderr)
communication channels between the caller and the child. In traditional
GUI programming this is often done by opening a pipe/socketpair in the
caller and passing a filedescriptor via commandline args to the child.
The recently added 'close all open files in the child after the fork'
feature in kprocess makes such an approach impossible. It would be
really nice, if this behaviour was the default, but could be turned off
by an appropriate flag at construction time.

BTW, "Xterm started from minicli really doesn't need to have the ksycoca
file open" is a weak argument w.r.t. the 'brute force' loop over all
possible fd's. Wouldn't it be better to fix minicli ? :-)

Greetings

	K-D
